Abstract:
ObjectiveTo investigate the correlation of Skp2,p27kiP1 and p21WAF1 expression with the clinicopathological features of ovarian serous cystadenocarcinomas.Methods Expressions of Skp2 ,p27kiP1 and p21WAF1 were examined by immunohistochemical staining in 124 epithelial ovarian tumors (25 serous cystadenomas, 19 borderline serous cystadenomas, and 80 serous cystadenocarcinomas) Results(1) The expression of Skp2 in serous cystadenocarcinomas (47.5％)was significantly higher than that in borderline serous cystadenomas (0％)and serous cystadenomas (0％)(P ＜ 0.001) .The p27kiP1 expression in serous cystadenocarcinomas (35.0％) was significantly lower than that in borderline serous cystadenomas(73.7％)and serous cystadenomas (80.0％) .The p21WAF1 staining frequency in serous cystadenocarcinomas (38.8％)was significantly lower than in borderline serous cystadenomas (73.7％)and serous cystadenomas (80.0％) .(2) The Skp2 protein expression in serous cystadenocarcinomas was positively correlated with clinicopathological stage,histological differentiation degree and lymph node metastasis of the tumors.The p27kiP1, p21WAF1 protein expression in serous cystadenocarcinomas was reversely correlated with clinicopathological stage and histological differentiation degree of the tumors(Ps ＜ 0.05) .(3) The Skp2 protein expression in serous cystadenocarcinomas was reversely correlated with that of p27kiP1 , p21WAF1.Conclusion The Skp2 protein expression in serous cystadenocarcinomas was increased and positively correlated with the clinicopathological features of ovarian serous cystadenocarcinomas.Skp2 protein expression was reversely correlated with p27kip1 ,p21WAF1.Skp2 protein expression may play an important role in the development and progression of serous cystadenocarcinomas.
